List Common Plant Species with Unisexual Flowers

Unisexual flowers are flowers that have only one sex organ—either male or female. Several plant species exhibit this characteristic, and they play an important role in the plant's reproduction.

Common Species with Unisexual Flowers

• Cucumbers (Cucumis sativus): Cucumbers have separate male and female flowers on the same plant, a characteristic of monoecious plants.
• Squash (Cucurbita spp.): Squash plants also have male and female flowers, with the male flowers usually appearing first in the growing season.
• Kiwi (Actinidia deliciosa): Kiwi plants are dioecious, meaning male and female flowers are found on separate plants, and only female plants bear fruit.
• Holly (Ilex aquifolium): Holly plants are dioecious, with distinct male and female flowers on separate plants, and only the female plants produce berries when pollinated.
• Mulberry (Morus spp.): Mulberry trees can be monoecious or dioecious, with separate male and female flowers on different plants in dioecious species, or on the same plant in monoecious species.
• Papaya (Carica papaya): Papaya is dioecious, with separate male and female flowers, although some varieties may have hermaphroditic flowers that can self-pollinate.
